IMMOBILIZER SYSTEM COMPONENT REPLACEMENT/KEY ADDITION AND CLEARING[ADVANCED
KEYLESS SYSTEM]

id0914008050b1

Foreword

• When performing the following procedures, the immobilizer resetting procedure using the M-MDS must also

always be performed: “Keyless control module replacement”, “PCM replacement”, “Steering lock unit
replacement”, “Keyless control module and PCM joint replacement”, “Keyless control module, PCM, and
steering lock unit joint replacement”, and “Key ID number clearing”. The engine will not start unless all work is
performed using the M-MDS.

• A card key that can start the engine is necessary for the key programming. If there is no card key that can start

the engine, perform the key programming after the card key programming. (See 09-14-33 CARD KEY ID CODE
REGISTRATION[ADVANCED KEYLESS SYSTEM].)

• There are two ways to add supplemental key: Using the M-MDS or using two keys that can start the engine to

program.

• When replacing any of the immobilizer system component parts, adding/clearing keys, or performing other

functions, refer to the following table and perform the applicable procedure (No.1 to 5).

• Verify that the room fuse is equipped.

Cautionary notes

1

Since two or more keys that can
start the engine are necessary,
make a spare key. Or program an
additional key.

• Programming key

• The M-MDS is necessary for the additional key

programming if “Customer spare key
programming disable” is performed before the
procedure using the M-MDS. In this case,
perform No. 2.

2

If there is only one key that can
start the engine, make a spare key.
If there is no key, program an
additional key.

• Programmed card

key

• Programming key

• M-MDS

Caution

• The following conditions may cause poor signal communication between the key and vehicle,

resulting in the engine not starting or a key registration error. Do not perform any work under the
following conditions:

— Placing the following items close to the key grip or contacting it.

• Spare keys

• Keys for other vehicles equipped with an immobilizer system

• Any metallic object

• Any electronic device, or any credit or other card with magnetic strips

• Do not place the following devices in the vehicle while programming, otherwise programming

cannot be performed:

— M-MDS

— Personal computer

— Devices that can send/receive the radio waves

Note

• The “valid key” used in this manual indicates the key that can start the engine.

• If the key adding, programming, clearing, and immobilizer system construction parts replacement are

performed, verify that the all keys can start the engine within 5 s after the procedure.

• When verifying that the engine starts, wait at least 5 s or more before starting the engine using the next

key.

• If the engine cannot be started using a programmed key, repeat the procedure from the beginning.

3

Replacing the PCM only.

• New PCM

• Programmed card

key

• Programming keys

(two or more)

• M-MDS

4

Changing the additional key
programming procedure. (Method
for programming other keys using
two keys that can start the engine
is disabled.)

• M-MDS

• The additional key programming using No. 1

cannot be performed after the procedure. It is
possible to restore the setting. For restoring the
setting, the M-MDS is necessary.

4

Changing the additional key
programming procedure. Allows
programming using two keys that
can start the engine.

• M-MDS

• New vehicles have this setting.

5

Clearing the programmed key ID
number.

• Programming keys

(two or more)

• M-MDS

• Carry out the following procedure using the M-

MDS, then go to 09-14-14 Procedure
— Ignition key CODE erase

5

Replacing all the keys. (Steering
lock unit is not replaced)

• Programmed card

key

• Programming keys

(two or more)

• M-MDS

5

Replacing the steering lock unit.

• New steering lock

unit

• Programmed card

key

• New keys (two or

more)

Replacing the keyless control
module.

• New keyless control

module

• Card key

• Programming keys

(two or more)

09-14

• Do not start the engine unless indicated in the procedure. If the engine is started during the programming

procedure, programming is stopped at that point. Repeat the procedure starting from the beginning if the
engine is started before completion.

• Do not place the card key in the vehicle or bring it within approx. 1 m of the vehicle unless indicated in

the procedure.

• Two or more key ID numbers must be programmed for the engine to start.

• A maximum of eight key ID numbers can be programmed for one vehicle. The M-MDS can be used to

verify the number of key ID numbers programmed to a single vehicle.

• Do not select a M-MDS screen menu other than one indicated in the procedure.

M-MDS Connecting Procedure

Caution

• Do not place the M-MDS in the vehicle while programming, otherwise programming cannot be

performed.

1. Fully lower the door glass.
2. Connect the M-MDS to the DLC-2.
3. Pull out the M-MDS cable from the door glass

opening and set the M-MDS outside the vehicle.

Caution

• Protect the cable and body contact area

with a clean rag, otherwise they could be
damaged.

No.1 Additional Key Programming Procedure (Using Two Valid Keys)

Caution

• Do not place the following devices in the vehicle while programming, otherwise programming

cannot be performed:

— Card key

— M-MDS

— Personal computer

— Devices that can send/receive the radio waves

Condition

• Have two or more valid keys.

Note

• A maximum of eight keys can be programmed for one vehicle. If key programming is not successful and

DTC 15 appears even though the procedure was performed properly, use the PID/data monitor function of
the M-MDS and verify the number of keys that have been programmed.

• If eight keys have already been programmed, and it is necessary to program other keys, the previously

programmed key ID numbers must first be cleared. To clear the key, refer to “09-14-13 No.1 Additional Key
Programming Procedure (Using Two Valid Keys)”.

Procedure

1. Prepare key 3 for programming.
2. Start the engine using key 1.
3. Verify that the security light illuminates for approx. 3 s, and then goes out.
4. Turn the ignition switch to the LOCK position.
5. Using key 1, turn the ignition switch to the ON position.
6. Verify that the security light illuminates for approx. 3 s, and then goes out.
7. Using key 1, turn the ignition switch to the LOCK position within approx. 4 s after the security light goes out.
8. Remove key 1.
9. Repeat Steps 2—5 using key 2 instead of key 1.

10. Repeat Steps 5—8 using key 3 instead of key 1.
11. If additional keys need to be programmed, repeat Steps 1—10, and replace key 3 in Step 10 with the key to be

programmed (key 4).

No. 2 Key Additional Programming Procedure (Using the M-MDS)
Condition

• There is only one valid key. Or, there is no valid key but there is a card key that can start the engine.

Note

• A maximum of eight keys can be programmed for one vehicle. If key registration is not successful and

DTC 15 appears even though the procedure was performed properly, use the PID/data monitor function of
the M-MDS and verify the number of keys that have been programmed.

• If eight keys have already been programmed, and it is necessary to program other keys, the previously

programmed key ID numbers must first be cleared. To clear the key ID number, refer to “09-14-13 No.1
Additional Key Programming Procedure (Using Two Valid Keys)”.

Procedure

1. Prepare key 1 for programming.
2. Start the engine using a valid key or card key.

Caution

• Do not place the card key in the vehicle when starting the engine with the valid key, otherwise

programming cannot be performed. If the engine is started with the card key, remove the card key
from the vehicle after the engine is started.

3. Verify that the security light illuminates for approx. 3 s, and then goes out.
4. Turn the ignition switch to the LOCK position.
5. Connect the M-MDS to the DLC-2. (See 09-14-11 Foreword.)
6. Using key 1, turn the ignition switch to the ON position.

Note

• Although the security light flashes and DTC 15 is displayed, this does not indicate an improper procedure.

Continue to perform the procedure as indicated.
